27 Claims. (01.141-7) Our invention relates to that class of milk bottle washers, now in common use, in which the bottles to be washed; are arranged in groups on appropriate carriers in endless conveyors normally traveling in uninterrupted order. Each group' comprising a number of bottles side by side in line with each other transversely of the machine, and these groups of bottles are advanced in unbroken series through the machine,

and at the point of delivery each group is discharged upon a conveyor leading to a bottle re-- filling machine. In a bottle washer of this class it is desirable that the clean bottles be delivered one complete group at a time at regular intervals so that a continuous series of saidgroups of bottles will be placed upon the delivery conveyor, resulting in a continuous supply of clean bottles equally spaced apart being fed to' the refilling machine.

In the normal use of machines of this class, an operator visually inspects the bottles when placed upon the discharge conveyor by the machine, and the machines now in use are so arranged that the operator may, if he sees a bottle visibly unclean or otherwise objectionable, remove a single bottle by hand and replace with another bottle which may not be perfectly clean or sterilized. r

The object of our invention is to provide an inspection compartment at the delivery point of a bottle washing machine, so constructed that the operator may remove objectionable or soiled bottles from the conveyor as soon-as discharged by the washing machine but cannot replace these by other bottles and that all bottles delivered from the machine in its normal operation shall be untouched by the operator's hands, and otherwise sanitary, thereby avoiding the possibility of delivering to the refilling machine unclean or unsterile bottles, and further to avoid the possibility of an operator touching with his hands any bottle which passes through the machine in the normal operation thereof and all bottles which may be touched by an operator when the inspection compartment is opened must be removed from the discharge portion of the washing machine and cannot be replaced.

A further object is to provide means whereby the inspection operator, upon observing an unclean or otherwise objectionable bottle within the inspection compartment, may readily, quickly and easily remove an entire group of bottles and at the same time automatically stop the bottle washing machine and conveyor, so that when the group in which the objectionable byttle was observed has been removed and the machine again started, the supply of bottles delivered to and placed upon the discharge conveyor will be in a continuous arrangement and equally spaced apart; and further in this connection it is our object to provide means whereby when the group of bottles has thus been removed and the door of the inspection compartment has been closed, the bottle washing machine and conveyor are automatically restarted.

A further object is to provide an inspection" compartment of this character with simple and inexpensive means for preventing water of condensation therein from dropping upon the bottles.

Referring to the accompanying drawings the reference numeral 10 is used to indicate generally the body of the bottle washing machine and its internal conveyor. The conveying mechanism Illa within the washing machine is' ppera-' tively connected with an electric motor I], and certain spray elements in the washing ,r'nechanism are operatively connected with an electric motor and pump unit, l2. There is also a conveyor enclosure l3a and a conveyor l3 for delivering washed bottles from the machine to a point distant, such, for instance, as a bottle refilling machine, indicated generally in Figure 8 by the reference symbol [3b. The conveyor [3 may be driven in any ordinary manner, such, for instance, as an electric motor, not shown. The. structural details of the parts just described are not herein fully illustrated and described but are simply shown as illustrative of one form 'at least of these bottle washing conveying and filling machines now in common use.

, Our improvement may be defined as an atv tachment to or improvement in bottle washing machines of this character, and consists of an improved enclosure over the bottle discharge portion of the bottle washer and is indicated generally by the reference numeral I4, having at one side a bottle deliveryopening l5 through which bottles on the conveyor l3 may pass out of the inspection enclosure and into the conveyor enclosure l3a which, as is clearly shown in Figures 8 and 9, is enclosed so that bottles can be removed therefrom only at the delivery end of the conveyor device. Reference herein to the delivery end of the conveyor l3 means the discharge end of the enclosed part thereof.

At the front of the enclosure is a hinged door I! provided with a handle l8. This door is preferably made of glass or other transparent material, so that the inspection operator may at all times visually inspect the bottles contained within the enclosure, and to aid in this inspec tion a lamp I 6 is provided within the enclosure. In Figure 1 the door is shown in its wide open position. Fixed to the door are two arms l9, extended downwardly from the position shown in Figure 1. These arms support the bottle engaging frame consisting of three rods 20, fixed at their ends to said arms l9. The arrangement of these parts is such that, when the door I I is in its closed position the rods 20 will stand above the space through which bottles are delivered from the washer and above and at the side of the conveyor l3 opposite from the door opening, and when the door is opened the rods '20 will engage all of the bottles upon the conveyor I 3 within the inspection enclosure and bodily move them to -the position shown in Figure 1. A stationaryplatform 2| is provided to support the bottles in this position. When the door [1 is in the position shown in Figure 1 the operator may remove all of the bottles contained upon the platform 2| and the rods 20, and these bottles must be removed before the washing machine can again be operated, because if the bottles are not removed and the door closed, these bottles would lie in a horizontal position across the conveyor l3 and prevent a new series 'of bottles from being placed in upright position upon the conveyor It by the automatic discharge I mechanism of the bottle washing machine. As will be seen in Figure 1 of the drawings, the lower one of the rods 20 is positioned somewhat in advance of the'others, so that upon opening the door I! it will first engage the bottles near the bottoms of the same, causing them to tilt back over against the other rods to thereby avoid the possibility of forcing the bottles from the compartment and breaking them. Further* more, the upper rods 20 are so positioned that when the door I! is open they will extend over the conveyor l3 and thereby prevent the manual return of bottles to the conveyor It.

For the purpose of preventing the removal by the conveyor l3 or replacing of bottles upon prevent any bottles being carried away by the conveyor, as well as to prevent an operator reaching a bottle within the enclosure at the time the door is beginning its opening movement. However, when the door I! is closed this closure stands in the rear of the opening I5 and does not. form a closure for said opening.

We have provided means whereby the opening and closing of the door l1 will properly control the operation of the bottle washing machine and its conveyors. For this purpose we have provided an electric switch, indicated generally by the reference numeral 22, shown in Figure 3, and which includes a spring actuated circuit closure '24 and a contact 25, and slidingly mounted in this switch is the push rod 26, and when the push rod 26 is moved downwardly the circuit will be opened and when pressure is removed from it the circuit will be closed by the spring 24. The electric current controlled by this switch mechanism is led by conductors 21 to a control box 28, and from this control box, mechanism not shown is provided for operatively con necting it with the motor and pump unit l2 of the washing machine. Another similar switch mechanism, indicated generally by the reference numeral 28 in Figure 4, is provided for controlling the motor of the conveyor mechanism Illa of the washing machine.-

For the purpose of opening'and closing these two switches at the same time we have provided a pivoted lever 32, normally held upwardly in a substantially horizontal position by a spring 3| to which is attached a cam follower 32a and a switch actuating bar 32 which, when moved downwardly by lever 30, depresses the push rods 26 in both switches. For the purpose of automatically operating the switches to open them instantly when the door I1 is opened, we have provided on the door I! a cam 23, shown in Figure 4, provided at its end adjacent the door I! with a recess or notch 24 below the datum plane 33a of the cam shown in dotted lines, and a stop 35 at the other end of the cam above the datum plane thereof. Said cam is normally held in engagement with the cam follower 22a mounted on the lever 30. This cam structure is such that when the door is in the position shown in Figure 4, the switches are open and the door is held in position by the engagement of the follower 32a with the recess adjacent stop 35, and when the door is closed, the cam will permit the lever 30 to move upwardly when the cam follower 32a engages the recess 24 which is below the datum plane' 32a of cam track 33, and thus close the switches. This switch mechanism actuated by the cam also functions to automatically stop the motors of both the washing machine pumping unit l2 and the washing machine conveyor mechanism I 0a when the door I 1 is opened, and

to automatically start both mechanisms when contact with the sterile washed bottles, and for this purpose we have provided a hood 26, immediately above the lamp II, which hood is provided with a discharge pipe 21 leading to the exterior of. the inspection enclosure. The heat from the lamp creates a current of air, passing upwardly through the discharge pipe 21 carrying 75 amaase with it such moisture within the inspection enclosure as might result in water of condensation.

In practical use with thisform of our invention the operator, positioned at the inspection enclosure, may clearly see all of the bottles as they are delivered from the washer to the delivery conveyor l3. In the event that he observes any one of the series of bottles delivered at one time to the conveyor I3 is not clean, or isotherwise defective, or improperly positioned, then he at once opens the door l'|. This automatically removes the entire series of bottles within the inspection enclosure, from the conveyor l3 and at the same time stops the entire washing procedure. The operator then removes all of the bottles thus discharged from the inspection enclosure. The operator is prevented'from returning any of the bottles thus removed, to the conveyor l3, because of the rods 20 operatively connected with the door H at the front, and the closure 22 covering the opening l5, and the washing machine cannot again be started until the bottles have thus been removed and the door l'l closed. If the operator attempted to close the door H with the bottles resting on the rods 20,

these bottles would be placed in horizontal position across the top of the conveyor I3, which in turn would prevent the bottle ejecting mechanism of the bottle washer from delivering bottles to the conveyor l3.

In Figure 5 we have shown a modified form of our invention which'diflers from the form illustrated in Figures 1 to 4, inclusive, primarily in that when the door I1 is opened, the bottles contained' upon that portion of the conveyor l3 which is within the inspection enclosure, instead of being withdrawn outwardly through the front of the inspection enclosure by the rod 4|, they are pushed back upon the discharge mechanism of the washing machine and thereby serve as obstructions to prevent further operation of the bottle washing machine without breaking bottles. In this formof the invention a bell crank lever 38 'is pivoted to the door l1 and a lever 39 is pivoted to a part of the inspection enclosure, and these two levers are pivotally connected at 40. A similar arrangement of levers 38 and 39 is provided at each side of the door opening. A rod 4| is extended across the inspection enclosure from one of the levers 39 to the other. When the door I! is closed this rod 4| stands in the position shown by dotted lines at 42, and when the door is opened this rod 4l moves across the top of the conveyor l3 and pushes the bottles backwardly upon the discharge mechanism of the bottle washing machine.

In this modified form we have also shown an electric switch mechanism for shutting off the motors H and I! for the washingand conveying mechanisms when the door is opened and which comprises a switch device, indicated generally by the reference numeral 43, and a switch closing arm 44 fixed to the lever 39, and these parts are so arranged that when the door I1 is in the position shown by solid lines in Figure 5, theswitch mechanism 43 is opened, and when moved to the position shown by dotted lines, the switch 43 is closed. Y

Another modification of our invention is illustrated in Figures 6 and 7, in which there is disclosed a means for automatically diverting the bottles from the conveyor l3 immediately after the bottles come out of -the inspection enclosure.

This mechanism comprises 'a pivoted arm 45 fixedly mounted just above the rear edge of the conveyor ii at the point where the conveyor passes out of the inspection enclosure through the opening l5. Fixed to the arm 45 is a short arm 45a below the conveyor, and this arm 45a is connected by a link 46, shown by dotted lines in Figure 6, with another similar lever 41 on the opposite side of the conveyor l3. This lever 41 is fixed to an upright shaft 48, to the upper end of which is-fixed a beveled pinion 49 enmeshed with a beveled pinion 50 on the hinge rod 5| fixed to the door I! of the inspection enclosure. Said link 46 is permitted to travel through a slot 46a in the table 52. Adjacent the outer ends of the arms 45 and 41 is a table 52 to receive the milk bottles thus diverted by said arms from the conveyor l3. In this modified form of the invention means are also provided for controlling the motors H and i2 of the washing machine and its conveying mechanisms Illa, by means of an electric switch, indicated generally by the reference numeral 53 and operated by an arm 54 connected with the arm 45, the arrangement being such that when the arms 45 and 41 are in the position shown by solid lines in Figure '6, the switch is open and the motors for the bottle washing mechanism and the conveyor Illa are stopped. However, the conveyor l3 may continue to operate, and when these arms 45 and 41 are returned to the position shown by dotted lines in Figure 6, the switch mechanism is closedand the washing machine mechanism is operated.

In practical use our invention is combined with a conveyor l3 enclosed by a cover I3a thereby insuring the passing of sterile bottles from the washer to a. filler l3b, and it is obvious that our invention does not'in any way interfere with the normal operation of the bottle washing machinery, nor does it interfere in any way with the normal inspection of the bottles by the operator. When the operator, however, sees a bottle which is not clean or which is otherwise defective or misplaced, all that is necessary is for him to open the door l1 and thereby remove all of the bottles within the inspection enclosure. During.

is provided with our improveddischarge enclosure from which the clean bottles are fed into a conveyor in which the bottles are not accessible to handling, it will be impossible for the operator of the washing machine to handle the bottles discharged by the washer before they, reach the bottle refilling mechanism as illustrated in Figure 8 unless they are completely removed from the enclosed discharge by means of the removin door provided therefor.
